--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:85d613da341b76308edea48359a5dbc7061937c4 commit r13-1190-g85d613da341b76308edea48359a5dbc7061937c4 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Jun 21 17:51:08 2022 +0200 libgomp: Fix up target-31.c test [PR106045] The i variable is used inside of the parallel in: #pragma omp simd safelen(32) private (v) for (i = 0; i < 64; i++) { v = 3 * i; ll[i] = u1 + v * u2[0] + u2[1] + x + y[0] + y[1] + v + h[0] + u3[i]; } where i is predetermined linear (so while inside of the body it is safe, private per SIMD lane var) the final value is written to the shared variable, and in: for (i = 0; i < 64; i++) if (ll[i] != u1 + 3 * i * u2[0] + u2[1] + x + y[0] + y[1] + 3 * i + 13 + 14 + i) #pragma omp atomic write err = 1; which is a normal loop and so it isn't in any way privatized there. So we have a data race, fixed by adding private (i) clause to the parallel. 2022-06-21 Jakub Jelinek <ja...@redhat.com> Paul Iannetta <pianne...@kalrayinc.com> PR libgomp/106045 * testsuite/libgomp.c/target-31.c: Add private (i) clause.
